SEPARATION OF CATALYST AND INERT HEAT PARTICLE AFTER AROMATIZATION OF AN ALKANE CONTAINING GAS STREAM

摘要

Implementations of the disclosed subject matter provide a process for the aromatization of alkanes in an alkane- containing gas stream which includes at least one alkane from among ethane, propane or butane. The process may include contacting the alkane-containing gas stream in a reactor comprising an aromatization catalyst particulate and an inert heat carrier particulate under alkane aromatization conditions to produce a product stream comprising aromatics and ethylene in the reaction zone. The inert heat carrier particulate may be separated from the aromatization catalyst particulate in a separation zone under separation conditions. The aromatization catalyst particulate may have a first minimum fluidization velocity and the inert heat carrier particulate may have a second minimum fluidization velocity which may be greater than the first minimum fluidization velocity. The ratio of the second minimum fluidization velocity to the first minimum fluidization velocity may be less than 200 and may be more than 15.
